In other projects Wikimedia Commons Wikibooks. This page was last edited on 25 January , at John Napier in described a system he called location arithmetic for doing binary calculations using a non-positional representation by letters.
Thomas Harriot investigated several positional numbering systems, including binary, but did not publish his results; they were found later among his papers.
Leibniz interpreted the hexagrams of the I Ching as evidence of binary calculus. Leibniz saw the I Ching hexagrams as an affirmation of the universality of his own religious beliefs as a Christian.
He believed that binary numbers were symbolic of the Christian idea of creatio ex nihilo or creation out of nothing. Now one can say that nothing in the world can better present and demonstrate this power than the origin of numbers, as it is presented here through the simple and unadorned presentation of One and Zero or Nothing.
In , British mathematician George Boole published a landmark paper detailing an algebraic system of logic that would become known as Boolean algebra.
His logical calculus was to become instrumental in the design of digital electronic circuitry. In November , George Stibitz , then working at Bell Labs , completed a relay-based computer he dubbed the "Model K" for " K itchen", where he had assembled it , which calculated using binary addition.
Their Complex Number Computer, completed 8 January , was able to calculate complex numbers. In a demonstration to the American Mathematical Society conference at Dartmouth College on 11 September , Stibitz was able to send the Complex Number Calculator remote commands over telephone lines by a teletype.
It was the first computing machine ever used remotely over a phone line. Some participants of the conference who witnessed the demonstration were John von Neumann , John Mauchly and Norbert Wiener , who wrote about it in his memoirs.
The Z1 computer , which was designed and built by Konrad Zuse between and , used Boolean logic and binary floating point numbers.
Any number can be represented by a sequence of bits binary digits , which in turn may be represented by any mechanism capable of being in two mutually exclusive states.
Any of the following rows of symbols can be interpreted as the binary numeric value of The numeric value represented in each case is dependent upon the value assigned to each symbol.
In a computer, the numeric values may be represented by two different voltages ; on a magnetic disk , magnetic polarities may be used.
A "positive", " yes ", or "on" state is not necessarily equivalent to the numerical value of one; it depends on the architecture in use. In keeping with customary representation of numerals using Arabic numerals , binary numbers are commonly written using the symbols 0 and 1.
When written, binary numerals are often subscripted, prefixed or suffixed in order to indicate their base, or radix.
The following notations are equivalent:. When spoken, binary numerals are usually read digit-by-digit, in order to distinguish them from decimal numerals.
For example, the binary numeral is pronounced one zero zero , rather than one hundred , to make its binary nature explicit, and for purposes of correctness.
Since the binary numeral represents the value four, it would be confusing to refer to the numeral as one hundred a word that represents a completely different value, or amount.
Alternatively, the binary numeral can be read out as "four" the correct value , but this does not make its binary nature explicit. Counting in binary is similar to counting in any other number system.
Beginning with a single digit, counting proceeds through each symbol, in increasing order. Before examining binary counting, it is useful to briefly discuss the more familiar decimal counting system as a frame of reference.
Decimal counting uses the ten symbols 0 through 9. Counting begins with the incremental substitution of the least significant digit rightmost digit which is often called the first digit.
When the available symbols for this position are exhausted, the least significant digit is reset to 0 , and the next digit of higher significance one position to the left is incremented overflow , and incremental substitution of the low-order digit resumes.
This method of reset and overflow is repeated for each digit of significance. Counting progresses as follows:. Binary counting follows the same procedure, except that only the two symbols 0 and 1 are available.
Thus, after a digit reaches 1 in binary, an increment resets it to 0 but also causes an increment of the next digit to the left:. In the binary system, each digit represents an increasing power of 2, with the rightmost digit representing 2 0 , the next representing 2 1 , then 2 2 , and so on.
The equivalent decimal representation of a binary number is sum of the powers of 2 which each digit represents. For example, the binary number is converted to decimal form as follows:.
Fractions in binary arithmetic terminate only if 2 is the only prime factor in the denominator. Arithmetic in binary is much like arithmetic in other numeral systems.
Addition, subtraction, multiplication, and division can be performed on binary numerals. The simplest arithmetic operation in binary is addition.
Adding two single-digit binary numbers is relatively simple, using a form of carrying:. Adding two "1" digits produces a digit "0", while 1 will have to be added to the next column.
This is similar to what happens in decimal when certain single-digit numbers are added together; if the result equals or exceeds the value of the radix 10 , the digit to the left is incremented:.
This is known as carrying. This is correct since the next position has a weight that is higher by a factor equal to the radix.
Carrying works the same way in binary:. In this example, two numerals are being added together: The top row shows the carry bits used.
The 1 is carried to the left, and the 0 is written at the bottom of the rightmost column. The second column from the right is added: This time, a 1 is carried, and a 1 is written in the bottom row.
Proceeding like this gives the final answer 2 36 decimal. When computers must add two numbers, the rule that: This method is generally useful in any binary addition in which one of the numbers contains a long "string" of ones.
It is based on the simple premise that under the binary system, when given a "string" of digits composed entirely of n ones where: That concept follows, logically, just as in the decimal system, where adding 1 to a string of n 9s will result in the number 1 followed by a string of n 0s:.
Such long strings are quite common in the binary system. From that one finds that large binary numbers can be added using two simple steps, without excessive carry operations.
You may get unexpected results with negative numbers, see http: By default, Perl treats the variables as floats and PHP as integers. I was able to verify the PHP use of the operator by stating "use integer;" within the Perl module, which output the exact same result as PHP was using.
However, this will not yield the same results. After about a half hour of banging my head against the wall, I discovered a gem and wrote a function using the binary-decimal conversions in PHP.
Be very careful when XOR-ing strings! My password hashing function was always returning the same hash Because I was XOR-ing it with a salt that was sometimes empty!
Be careful of order of operations. Use at your own peril. In order to get the result I expected 01 , it was necessary to AND the result with the number of bits I wanted: Be aware that all return values will have zeros removed from the left until they reach a bit that is set to 1.
Continuing the above example, the following: This is probably a good thing. If what you want is just to reverse a string of bits without any interpretation, you can use a function like this: You can then treat it as a binary number, use bindec to turn it into a decimal, or whatever you want.
I hope this helps someone as much as it would have helped me a week ago! I found the bit limitation on the bitwise ands to be a bit frustrating in large scale permission control applications.
I have a situation involving page-level access with more than 50 pages. I was able to workaround the limitation by adding a loop that dropped 31 bits off of the right until the resource identifier bit is within the first For those who were searching for a way to actually rotate the bits of a number, here are some little functions I wrote: For those like me who are trying to do bit masking with very large numbers, here is a useful function to do the work for you.
The following function will perform a bit left shift on a bit machine: By this I mean managing a set of options which can either be ON or OFF, where zero or more of these options may be set and each option may only be set once.
Here is the code: You can store loads of flags in a single integer.
